So if you have a Bukkit plugin, here's what I think you are meant to do:

1. Create a new folder2. Put this file and whatever Bukkit file you wish to convert in that folder3. Open notepad.exe (for Windows), and copy the line above the (java -jar one)4. In the save as menu, change the file type to "All files" and change the name to "RunIt.bat" and hit save5. Run the file.6. However it works, whatever file appears next is the Rainbow file you can use as a plugin!
